Introduction

The challenges of development, in a play such as the Bakken formation, include managing vast amounts of data coming in on a daily basis and using the data to make timely, intelligent decisions. Geomodels organize, track, and incorporate large amounts of data into a single environment; managing data from a single environment leads to making more informed decisions about well spacing, perforation locations, and target interval selection.

The data stream of wells in unconventional plays usually includes well log data, mud logging information, geosteering data and core information. Straightforward geomodeling workflows are able to incorporate this information with existing data such as seismic data, geological interpretations and petrophysical, geomechanical, or facies models. As new data is added to the environment, rapid model updates can be performed to ensure that the models are up to date and useful. Futhermore, geomodeling efforts foster collaboration and synergy amongst the subsurface disciplines and has benefitted Hess Corporation's Bakken asset by creating a better regional and sub-regional understanding of the basin by consolidating available technical information. Finally, the geomodeling work has created a more complete understanding of the geosteering results, fluid distributions, completion and reservoir simulations, and ultimately has given us a better understanding of productivity in the basin.
